Thread: My method disappeared!!

What happends here, and how do i get around it?

Code:

class Base
{
public:
	int foo(int, int)
	{
		//implemented
	}
	virtual int foo(int) = 0;
};

class Concrete: public Base
{
public:
	virtual int foo(int)
	{
		//implemented
	}
};

Creating a Concrete object my compiler does not resolve the
foo(int,int) method.
I get the following error using VS.net 2003.

Code:

foo' : function does not take 2 arguments

I guess i could solve it doing something like

Code:

class Base
{
public:
	virtual int foo(int, int)
	{
		//implemented
	}
	virtual int foo(int) = 0;
};

class Concrete: public Base
{
public:
	virtual int foo(int)
	{
		//implemented
	}
	virtual int foo(int x,int y)
	{
		return Base::foo(x,y);
	}
};

But i think that should not be necessary?
Help!
